IMPROVEMENT IN GRIDIRONS.

Specification forming part of Letters Patent No, 215,711, dated May 27,1879 application filed March 17, 1879.

To all whom it may concern:

Be it known that I, J MOGREGOR ADAMS, of Chicago, in the county of Cookand State of Illinois, haveinvented a new and useful Improvement inGridirons, which is fully set forth in the following specification,reference being had to the accompanying drawings, in which Figure 1 is aplan view of a gridiron containing my improvement, a portion of theupper plate being broken away; Fig. 2, an end elevation of the same; andFig. 3, a transverse section taken on the line a: 00, Fig. 1.

My invention relates to that class of gridirons in which a closedcorrugated plate is used for supporting the meat, as is shown in LettersPatent No. 181,823, granted to George Cornwall, September 5, 1876 andthe object of my improvement is to adapt this style of gridiron to beused on coal-oil or gas stoves.

The gridiron shown in said patentis adapted for use with the stove-topof an ordinary cookstove; but, constructed as there shown, it cannot beused with the coal-oil and gas stoves now in common use, for there mustbe provision for a draft up, through, and out of the utensil, as well asmeans for holding it on the stove.

The invention consists in providing the gridiron with a bottom in whichthere is an opening corresponding to the griddle-hole in the top of thestove, and having outlets at the side for the escape of the heatedgases, so as to provide for the necessary draft.

In the drawings, A represents the bottomplate of the gridiron, which ismade, preferably, of rectangular form, and has an opening, a,corresponding to a griddle-hole in the stovetop, or, where none is used,to the opening at the top of the stove. Around this opening is adepending flange, a, by means of which the gridiron is held to thestove, either by being placed within the griddle-hole or within orwithout the casing at the top of the stove. This flange also serves toconduct all the hot gases up into the space above the bottom-plate.

The plate A is surrounded by upright flanges. The two end flanges, B,are slightly inclined, as shown in Fig. 2 of the drawings, and haverecesses I) cut in them. The back side flange, O, is flush with thewider ends of the side flanges, and is provided with a series ofnotches, c. The front side flange, D, is somewhat narrower than theflange G, and is provided with a nose or spout, d. A little way backfrom the front flange, D, is another upright flangeor partition, E, ofabout the same height as flange D, and provided with a series ofnotches, c, in its upper edge, corresponding with those in the backflange, O.

The plate F is made of suitable size to cover the entire space betweenthe end flanges, B, and the flanges O and E, and is corrugated in such amanner that the corrugations exactly lit the angles or notches in theflanges O and E. The end edges of this plate may be bent over the endflanges, B, and hold the former in place, as shown in Fig. 3 of thedrawings; or the corrugated plate or cover may be secured in any otherway convenient for this purpose.

It will be seen that the corrugated plate is inclined downward towardthe front of the bottom-plate A, and this corrugated plate being adaptedto receive the meat for broiling, the juices will run down into thespace between the flanges D and E, from which they may be poured, itbeing understood, of course,

that when the broiler is applied to the stove the bottom-plate issubstantially level.

It will be evident, from the description above given, that when thisgridiron or broiler is put in place upon a gas or coal-oil stove, allthe hot gases are conducted up into the space underneath the corrugatedtop-plate and between, it and the bottom-plate, while at the same timethe apertures I) at the ends of the broiler afford means for the escapeof the hot gases, which is an absolute necessity in stoves of this kindin order to obtain the necessary draft. All of the advantages attendingthe broiler described in the patent mentioned above are, therefore,secured in an implement adapted for use with coal-oil stoves.

The exit openin gs for the escape of the gases may be made in the backflange instead of at the ends, or they may be made in all of theflanges, if desired 5 and other changes may be made in the preciseconstruction of the broiler as described, without materially affectingthe operation thereof.

Having thus described my invention, what I claim as new, and desire tosecure by Letters plate with an opening, whereby it is fitted to Patent,isthe stove, inclined flanges B, having recesses 1.
